东北地区马铃薯甲虫监测与入侵风险分析

Monitoring of Leptinotarsa decemlineata in Northeast China and Analysis of Its Invasion Risk

在利用多种方式进行马铃薯甲虫识别、危害及防控技术宣传,增加东北地区马铃薯产区对马铃薯甲虫的认知程度的基础上,于2009和2010年度,在我国东北吉林省、辽宁省、黑龙江省和内蒙古东部地区设立了马铃薯甲虫监测点32个,调查面积439 hm2,监测面积193万hm2,未发现马铃薯甲虫。根据马铃薯甲虫发生及传播特点,以及在俄罗斯远东地区的发生情况,进一步提出了我国东北地区马铃薯甲虫入侵的风险性及应对策略。

Several methods were employed to disseminate the identification,damage,the prevention and control technology,promote the recognition rate of the quarantine pest Leptinotarsa decemlineata in the potato planting area in northeast China.On that basis,32 stations were set for L.decemlineata monitoring in Jilin Province,Liaoning Province,Heilongjiang Province and eastern region of Inner Mongolia in 2009 and 2010.The investigation area and monitoring area was 439 hectare and about 1.93 billion hectare,respectively.The pest was not detected.Further more,the invasion risk was analyzed and control strategy of L.decemlineata were put forward according to its distribution and spread characteristic as well as its dispersal in the Russian Far East.
